This time, the Sonnet Rack Mac Pro allows users to rack mount one or two Mac Pro machines in a 4U space. The unit includes a front panel power button with USB 3.0 port for each machine, plus a second USB 3.0 port, a Gigabit Ethernet port, and an HDMI connector on the back of the rack for each Mac Pro.
There are no rear Thunderbolt ports because, Sonnet says, there are no panel-mount Thunderbolt connectors available. There is, however, room inside the rack for Thunderbolt cables to be attached, and the company says it is "fairly easy" to directly connect Thunderbolt cables and they can be secured to the Mac Pro so they can not be accidentally unplugged.
The Rack Mac Pro also supports the mounting of Thunderbolt to Fibre Channel adapters like the Promise San Link2.
Pricing is expected to be $599 to rack mount a single Mac Pro, with an add-on to mount a second Mac Pro available for $299. Availability is likely to come in June alongside the previously announced combination enclosure and expansion chassis.
